Stadium MK is still oddly indistinguishable in texture from the Ikea megastore with which it shares a plot, its main entrance reminiscent of the marketing suite of a rather swish new suburban residential development.

With the new Gansevoort Hotel on Park Avenue South and 29th Street, and Eataly, a 50,000-square-foot Italian megastore, both opening this fall, this "un-neighborhood" — as Corcoran Group agent Shakti C'Ganti puts it — is experiencing a renaissance after years of being a no-man's land sandwiched between the Flatiron, Gramercy and Murray Hill districts.

In September, Mr. Lissoni will inaugurate his latest hotel design project, the five-star Conservatorium Hotel in Amsterdam, and stop by Paris for the opening of a Lissoni-designed Benetton megastore on Boulevard Haussmann.

That's not all Jump's bought in the Barcelona megastore: he also made it on to the pitch at Villarreal during Arsenal's Champions League semi-final there in 2006 and gave a Barça shirt to Henry, who moved to the Camp Nou in the summer.
